KARL I-IUTTER, OF NEV YORK, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 562,225, dated. June 16, 1896.

Application filed February 18, 1896. Serial No. 579,730. (No model.)

To all whom t may concern,.-

Be it known that I, KARL IIUTTER, a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to bottle-Stoppers, and has for its object to produce a bottle-stopper which will constitute a double-seal stopper which will contain a minimum of elastic material and will require a minimum amount of pressure to seat it in the bottle. I will explain that by a double-seal stopper I mean one which will seal both the neck and the mouth or lip of the bottle.

In setting forth my invention I will have reference to the accompanying drawings, and will now proceed to point out and claim the novel features of my stopper.

In the dra\vings,Figure lis a section through a bottle-neck, showing my stopper in position above the mouth of a bottle and about to be entered thereinto. Fig. 2 is a section exhibiting the bottleneck and stopper shown in Fig. l, the section being taken transversely through the center of the stopper and the aperture therethrough. Fig. 3 is a plan view of the elastic plug which forms part of my stopper, and Fig. 4C is a section therethrough on line 4 4 of Fig. 3.

In the drawings, A is a bottle-neck which is surrounded by the usual neck-wire a, provided with the usual eyes for the reception of the yoke-lever b, which in turn receives the ends c of the bail-wire, which passes through the aperture d in the plug e, thereby carrying the plug. The plug is provided with a knob e', behind which is a neck e2, from which the sides e3 slope away to the body of the plug. This plug is preferably made of porcelain or other hard substance. Porcelain, however, being cheap and incorrodible, is admirably suited for the purpose. The more elastic member of the stopper is constituted by the elastic plug B, which consists of an annular member b,combined with an annular member b2 of smaller diameter and smaller annulus, so that the edge b3 `of the annulus b forms a shoulder. This elastic member I preferably make of rubber for reasons of economy and efficiency, and in the present instance have shown it as having its annulus b2 of considerably smaller diameter than the bottle-mouth, and its annulus b of somewhat greater diameter than the bottle-mouth when the plug B is on the plug e, which will'be clearly seen by an inspection of Fig. 1. In this figure, as before pointed out, the stopper is shown as about to be entered into the bottle-mouth, while in Fig. 2 the stopper is shown as actually entered.

` In Fig. 2 I have clearly shown the formtaken by the rubber plug B, whence it will be noted that the bottle-mouth is doublysealed. First, there is a seal around the mouth between the lines l 2, which is the primary seal, and the secondary seal around the lips of the mouth, as indicated at 3. So therefore there is not only an intern al or inside mouth-seal, but also an external or lip seal. It will also be noted that a very small amount of rubber has been used to effect this double seal and that the stopper will efficiently seal hair-lipped bottles and chipped bottles.

It will be seen that the larger or elastic member b projects away from the tapered plug above the same and thereby leaves a vacant space between the outer rim or edge of said elastic member and the tapered portion of the said plug. This serves the function of allowing the elastic member to be stretched while being pressed into the bottle-mouth, thereby snugly fitting the tapered portion of the plug and the interior of the bottle-mouth, as is clearly shown in Fig. 2. It also serves the function of great saving in rubber, since by so stretching and compressing the rubber upon the application of the stopper to the bottle the flange b' forms in reality a better interior'seal than has heretofore been accomplished by a relatively much larger quantity of rubber.

I am aware that a hanged elastic plug is not new, and I do not mean to be understood as claiming such a plug broadly, but

Vhat I do claim, and desire to secure by Letters Patent, is-

A stopper comprising a tapered plug, and a stepped elastic stopper member carried upon the same and leaving a space between the outer edge of the upper andlarger stepped portion of said member and said plug, substantially as described and for the purpose set forth.
